How Do You Find the Y-Coordinate of a Point on a Line If You Have a Graph?

Note:

Looking at the graph of an equation? Trying to figure out the y-value of a point on that graph? Learn how to answer that question by watching this tutorial! This tutorial shows you how to use the graph of a equation to find the y-value of a point.

Working With Graphs

Graphing a function? It would be really helpful if you had a table of values that fit your equation. You could plot those values on a coordinate plane and connect the point to make your graph. See it all in this tutorial!

Finding Slopes

Trying to find the slope of a graphed line? First, identify two points on the line. Then, you could use these points to figure out the slope. In this tutorial, you'll see how to use two points on the line to find the change in 'y' and the change in 'x'. Then, you'll see how to take these values and calculate the slope. Check it out!
